php - 在 Woocommerce 中仅向 PayPal 发送订单号而不是商品名称

Question

在 Woocommerce 的 PayPal 标准网关中，我想让 Woocommerce 只发送“订单号”作为购物车中的唯一项目，而不是逐项产品列表。

为此，我尝试在此处编辑负责发出 PayPal 请求的类: woocommerce/includes/gateways/paypal/includes/class-wc-gateway-paypal-request.php

我试图编辑 get_order_item_names() 函数以返回 "invoice"。 $order->get_order_number() 作为唯一商品的名称，但它并不成功，因为如果有多个商品，则仅返回第一个商品和订单号，其他商品保留。

此外，我还添加了 add_line_item() 函数，因为要达到目的，实际上应该只有“item_name_1”，其中包含卡的总金额。

$this->line_items[ 'item_name_' . $index ]   = $this->limit_length( $item['item_name'], 127 );
$this->line_items[ 'quantity_' . $index ]    = $item['quantity'];
$this->line_items[ 'amount_' . $index ]      = $item['amount'];
$this->line_items[ 'item_number_' . $index ] = $this->limit_length( $item['item_number'], 127 );

这里也没有成功。

非常感谢您的帮助。

Recommendation: You should really avoid overriding woocommerce core files.

相反，您可以使用在这种特殊情况下过滤器钩子(Hook)woocommerce_paypal_args，其中您将能够操纵参数 在 get_request_url() 函数中使用(它将获取订单的 PayPal 请求 URL)。

1) 测试并获取发送的数据

只是为了注册并获取发送到 paypal 的参数，我以这种方式使用了钩子(Hook):

add_filter('woocommerce_paypal_args', 'custom_paypal_args', 10, 2 );
function custom_paypal_args ( $args, $order ) {
    // Saving the data to order meta data (custom field)
    update_post_meta( $order->get_id(), '_test_paypal', $args );
    return $args;
}

代码位于您的事件子主题(或主题)的 function.php 文件中或任何插件文件中。

现在我可以简单地使用这个(设置正确的订单 ID)获取数据:

$order_id = 648;
$data_sent_to_paypal = get_post_meta( $order_id, '_test_paypal' );
echo '<pre>'; print_r( $data_sent_to_paypal ); echo '</pre>'; 

或者在钩子(Hook)中(在这个例子中仅对管理员可见的商店页面):

// Only visible on shop pages by admins
add_action( 'woocommerce_before_main_content', function(){
    // Only visible by admins
    if( ! current_user_can( 'manage_options' ) ) return;

    $order_id = 648;
    $data_sent_to_paypal = get_post_meta( $order_id, '_test_paypal' );
    echo '<pre>'; print_r( $data_sent_to_paypal ); echo '</pre>';
}, 10, 0 );

这给了我这样的输出(对于 2 种产品和不同数量):

Array
(
    [0] => Array
    (
        [cmd] => _cart
        [business] => email@example.com
        [no_note] => 1
        [currency_code] => EUR
        [charset] => utf-8
        [rm] => 2
        [upload] => 1
        [return] => https://example.com/checkout/order-received/8877?key=wc_order_55445ndfgbulfdf&utm_nooverride=1

        [invoice] => pp-8877
        [custom] => {"order_id":8877,"order_key":"wc_order_55445ndfgbulfdf"}
        [notify_url] => https://example.com/wc-api/WC_Gateway_Paypal/

        [address2] => 
        [city] => wef
        [state] => AR
        [zip] => 43242
        [country] => US
        [email] => myemail@example.com
        [night_phone_a] => 078
        [night_phone_b] => 653
        [night_phone_c] => 6216
        [no_shipping] => 1
        [tax_cart] => 16.55
        [item_name_1] => Test Product - Service
        [quantity_1] => 1
        [amount_1] => 71
        [item_number_1] => 
        [item_name_2] => Test Product 1
        [quantity_2] => 1
        [amount_2] => 66
        [item_number_2] => 
        [item_name_3] => Test Product 2
        [quantity_3] => 1
        [amount_3] => 120
        [item_number_3] => 
        [item_name_4] => Test Product 3
        [quantity_4] => 1
        [amount_4] => 45
        [item_number_4] => 
    )

)

正如您现在看到的，使用 woocommerce_paypal_args，您将能够更改或删除任何参数。

There is always only one: 'item_name_1', 'quantity_1', 'amount_1' and 'item_number_1' with always index 1 sent to paypal.

2 处理发送的数据 (示例):

我们仍然可以使用 woocommerce_paypal_args，例如 'item_name_1' 键上的过滤器 Hook ，用订单号替换商品名称，随心所欲:

add_filter('woocommerce_paypal_args', 'custom_paypal_args', 10, 2 );
function custom_paypal_args ( $args, $order ) {
    $$args_keys = array_keys($args);
    $i = 0;
    // Iterating through order items
    foreach( $order->get_items() as $item_id => $item_product ){
        $i++; // updating count.
        if( ! empty($args["item_name_$i"]) ){
            // Returning the order invoice in the item name
            $args["item_name_$i"] = "invoice #" . $order->get_id();
        }
    }
    return $args;
}

代码位于您的事件子主题(或主题)的 function.php 文件中或任何插件文件中。

代码已经过测试并适用于 WooCommerce 3+

To finish: As you get the WC_Order object as argument in your hooked function, you can use it to get any data from the order, and manipulate as you like the data sent to paypal gateway.
